ChEBI definition: A major geometrical isomer of roxithromycin.

Other ChEBI roles (chemical / environmental): xenobiotic, environmental contaminant.

Also known as: NSC-758443, Roxithromycin, Roxithromycine, Roxitromicina, RU 28965, RU 965, RU-28965, RU-965, Rulid, roxithromycin, roxithromycin monohydrate, ROXITHROMYCIN

Patent coverage: 8,798 distinct patent families (25,469 SureChEMBL compound mentions), from 1 matched compound structure(s). Mentions count patents naming the compound (not distinct inventions), so promiscuous / reference molecules inflate the mention figure — families are the dedup metric.

Pharmacology

Pharmacogenomics

No PharmGKB pharmacogenomic data curated for this drug.

Molecules sharing ≥1 of this drug’s curated primary targets, merged from two biobtree sources and ranked by shared-target count, then clinical phase: ChEMBL clinical-stage candidates (development phase ≥2) and PubChem drug-class bioactivity (approved / known drugs acting on the target). Deduplicated by drug name; the drug’s own salt forms are excluded. Note: for a drug with few primary targets a shared-target match can reflect off-target / promiscuous binding rather than the same therapeutic mechanism — the phase ordering surfaces bona-fide therapeutics first.
